Valve replacement is a surgical procedure to replace a heart valve for the treatment of valve disease. Post-operative survival varies depending on many factors, including the patient’s age, overall health, and the specific procedure performed (repair or replacement). The following are some of the factors associated with postoperative survival. 1. Age at surgery and underlying health Younger patients with good underlying health usually have a better prognosis after valve surgery. However, many older patients may also have significantly improved quality of life and survival after surgery. 2. Postoperative rehabilitation and lifestyle changes Postoperative rehabilitation programs and lifestyle changes (e.g., maintaining a healthy diet, exercising moderately, and following medical advice) are important for improving postoperative survival. Taken together, many patients may experience prolonged survival and improved quality of life after successful valve surgery. Survival may vary depending on the individual’s condition, so consult with your doctor for more accurate prognostic information.
